I've had the exact same problem with the 9625 drivers on a Suse 10.1 system. Try grabbing the 9631 drivers instead; they seem to be working for me.

Incidentally, the latest released drivers on Nvidia's website are actually kind of hard to get to. For whatever reason, depending on how you navigate their site, you'll end up with it telling you a different version is the latest. Whenever you go to their drivers page, instead of using the listboxes to determine which drivers you want, look up a few lines and click on the link for Linux drivers. That link always points to the latest ones, unlike the other browsing method..
